Description
Technical Field

Background
In the LED chip market, the throughput requirement is very high, and the pursuit of how to improve the productivity and reduce the cost is extremely severe. Particularly on a vacuum coating post, because a mode of frequently and manually loading and unloading the substrate is adopted, the convenience of operators is further pursued to be improved so as to reduce the repeated labor time; the working efficiency is improved for operators, the yield is increased for enterprises, and the profit is improved.
The manual substrate loading and unloading mode is that an operator places an empty tray on a workbench, takes out a substrate (with the thickness of about 365 microns) to be coated from a wafer box by using a suction pen, places the substrate into the empty tray (tray groove), and then places the substrate into a positioning jig (positioning ring); then, repeatedly taking out the substrate and putting the substrate into the tray and putting the substrate into the positioning jig until the tray is filled with the substrate; and finally, fixing by using a fixing clamp, and finally putting into coating equipment (a vertical through type sputtering vacuum device) for vacuum sputtering coating.
Because the tray has more grooves for placing the substrate, the positioning ring must be matched and placed when the substrate is placed each time, which causes overlong loading and unloading time; since the positioning ring is directly placed (rigidly contacted) on the substrate, if the locking force of the fixing clamp is too large or the substrate is not placed in place, the positioning ring crushes the substrate when the fixing clamp is locked. Due to the shape structure of the positioning ring, the phenomenon of rolling and dropping is easy to occur, and the positioning ring is deformed after dropping, so that the positioning ring cannot be installed in the groove of the tray any more, and subsequent correction operation or new product replacement is needed.
SUMMERY OF THE UTILITY MODEL
The utility model mainly solves the technical problem of providing a substrate fixing clamp, which can change the rigid contact of the substrate into the flexible contact of the spring sheet type by fixedly arranging the spring sheet on the fixing clamp body, reduce the use of the positioning ring and solve the problems of complicated loading and unloading, deformation and the like caused by the positioning ring; and the pressure of the elastic sheet on the substrate can be changed by adjusting the thickness of the fixing block, so that the fixing effect on the substrate is ensured.
In order to solve the technical problem, the utility model discloses a technical scheme be: provided is a substrate fixing jig including: the fixing clamp comprises a fixing clamp body, a fixing piece and a spring piece, wherein the fixing clamp body is fixedly connected with a tray and used for fixing and limiting a substrate in a tray groove, the fixing clamp body is detachably arranged on the fixing clamp body and correspondingly located on the fixing block in the tray groove, and the spring piece is detachably arranged on the fixing block and used for abutting against the substrate.
Preferably, the number of the elastic sheets is two, and the two elastic sheets are symmetrically fixed on the fixed block.
Preferably, the elastic sheet is S-shaped, one end of the elastic sheet is fixedly connected with the fixed block, and the other end of the elastic sheet is defined as a limiting end and can be abutted against the substrate; the directions of the two elastic sheet limiting ends are opposite and not opposite.
